The Auri™ TX2N is a sleek, low-profile transmitter designed for professional installations, resembling a Wi-Fi access point. It features a discreet logo, multicolour status indicator, and side-mounted balanced analogue mic/line inputs, supporting mono, stereo, or dual mono configurations. A single ethernet connection manages PoE, network/PC control, and Audio over IP, with an option for Dante® network audio. It also includes a balanced line output and USB-C for optional power. A versatile ceiling/wall mounting bracket is included for easy installation. Available in white and black finishes.
